Clock Input. Each clock pulse executes the step-up or step-down of the resistance. The direction is determined
by the state of the U/D pin. CLK is a negative-edge trigger. Logic high signal can be higher than V
than 5.5 V.
Up/Down Selections. Logic 1 selects up and Logic 0 selects down. U can be higher than V
Resistor Terminal A. GND ≤ V
Common Ground.
Wiper Terminal W. GND ≤ V
Chip Select. Active Low. Logic high signal can be higher than V
Positive Power Supply, 2.7 V to 5.5 V.
